Study of Millimeter‐Wave Rotational Spectra of Phosphorus Trifluoride in Ground,v 2 = 1 and v 4 = 1 States
The millimeter‐wave rotational spectra of the ground and excited vibrational states v 2 =1 and v 4 =1 of the symmetric top molecule, PF 3 , have been analyzed again. The B 0 = 7819.9907(13) MHz, D J = 7.84984(41) kHz, D Jk = ‐11.7644 (11) kHz, H J = 15.678 (36) mHz, H Jk = ‐66.46 (12) mHz and H kJ =...
